Not an electrician but have been doing up my old house....
Lights here in the UK are usually on a "loop in system". So there is power flowing through the loop even if the specific light fixture is off. The plastic part with the connections is known as a ceiling rose
Behind the plastic should be three cables. One coming from the prior light fixture, one
Going to the next, and one to the switch.
There needs to be a circuit at all times even if your light is off... Otherwise the switch would turn off all the lights down the line.
The middle three should be all the lives. The flex N should be the two neutrals from the loop and the neutral from the light fitting. The remaining two should be the switched live (black with red tape) and the live going to the fitting.
At a glance it looks like it's wired correctly. Id assume it's probably the light fitting or ceiling rose at fault. You can get a new one for less than a fiver.
